Steel Locknuts with External-Tooth Lock Washer

Also known as Keps and K-Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance. Height includes the thickness of the washer. A zinc plating provides corrosion resistance in wet environments.

Metric Steel Locknuts with External-Tooth Lock Washer

Also known as Keps and K-lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance. Height includes the thickness of the washer. A zinc plating provides corrosion resistance in wet environments.

Stainless Steel Locknuts with External-Tooth Lock Washer

Standard Hex Nut Profile

Narrow Hex Nut Profile

These stainless steel locknuts have good chemical resistance and may be mildly magnetic. Also known as Keps and K-Lock nuts, they have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance. Height includes the thickness of the washer.

Stainless Steel

Black-Oxide Stainless Steel

These locknuts have good chemical resistance and may be mildly magnetic. Also known as Keps and K-Lock nuts, they have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance. Height includes the thickness of the washer.

Metric Steel Nonmarring Locknuts with Spring-Lock Washer

A conical washer acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. They have a smooth rim to resist scratching materials when tightened. Also known as Keps and K-lock nuts. Height includes the thickness of the washer.

Zinc-plated locknuts have an outer layer of zinc that provides corrosion resistance in wet environments.

Blackoxide locknuts are mildly corrosion resistant and have a dark surface color.

Steel Nonmarring Locknuts with Spring-Lock Washer

These locknuts have a curved washer that acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer. Also known as Keps and K-lock nuts. A zinc plating provides corrosion resistance in wet environments.

Flanged Push Nuts

A flange distributes the load over a large area and reduces stress where the nut meets the material surface. Push them over threads to hold fasteners in light-duty holding applications. A zinc plating provides corrosion resistance in wet environments.

Flanged Push-On External Retaining Rings

The wide flange provides better load distribution than standard external push rings and can be used to cover oversized holes. Also known as thread cutting nuts. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip.
